LOCOMOTIVE HEADLIGHT.

Application nledla'nnary 5, 1927. :Serial No. 159,177.

This invention relates to headlight mechanism designed chiefly for locomotives,

The invention utilizes the movement of.

the pilot truck of the locomotive as means for operating the mechanism to turn the headlight to the right or to the left, as occasion may require to insure the lighting up of the track ahead a. safe distance.

The invention provides a mechanism which may be readily installed upon locomotive engines in service without necessitating any change in the construction or arrangement of parts and without entailing any very great expense consistent with the desiredadvantages.

WVhile the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construct-ionmay be resorted to within the scope of the invention as claimed, without departing from the spirit there-0f.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,

Figure 1 is a fragmentary view of the forward portion of a locomotive engine provided with a headlight mechanism embodying the invention, the pilot truck being in section. v

Figure 2 is a view of the pilot truck as seen from below.

Figure 3 is a detail sectional view on the line 33 of Figure 2 looking in the direction of the arrows.

Figure 4 is an enlarged sectional detail on the line 4-.- i of Figure 2, looking in the direction of the arrows.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

A suflicient amount of the front portion of a locomotive engine is illustrated to demonstrate the application of the invention, the numeral 1 designating the boiler, 2 one of the cylinders, and 3 the pilot truck which is of the floating type to receive a lateral and a tilting movement. A pillow blocker rises from the frame of the pilot truck and engages a rocker bearing 5 provided upon the bottom side of .theengine, and in this man ner the forward portion of the locomotive.

is supported upon the pilot truck to admit of the latter having a relative tilting and pivotal side movement. 1

A vertical post 6 is located forwardly of the boiler 1 and is mounted in suitable bearings provided upon the front of the boiler and the truck structure upon which the boiler and cylinders are mounted. The headlight 7 is mounted upon the post 6 to turn therewith and is adjustable vertically thereon so as to be located at the required elevation. An arm 8 is clamped or otherwise secured to the lower end of the post 6 and projects laterally and is pivoted to the laterally curved end 8 of a longitudinally disposed. bar 9 arranged beneath the top portion of the pilot truck. The numeral 10 designates the pivot connection between the arm 8 and the lateral extension 8 of the bar 9, and provision is had for adjustingthe same by providing a plurality of openings in one of the parts, as indicated most clearly in Figure 2. j

A king bolt 11 or like part, projects downwardly from the sub-structure of the locomotive, and a bar 12 is pivotally mounted thereon adjacent one end, the opposite end of said bar being pivoted to the top portion of the truck frame, as indicated at 13. The adjacent ends of the bars 9 and 12 project laterally in the same direction as indicated at 14 and 15, and are pivotally connected at their extremities, as indicated at 16. As a result of this arrangement a relative lat eral movement of the pilot truck 3 effects a pivotal movement of the bar 12 and a longitudinal movement of the bar 9, and since the latter is pivotally connected tothe arm 8 the latter receives a pivotal movement which results in a turning of the post 6 and the headlight 7 mounted thereon. The parts are of such construction and relative arrangement as to effect a turning of the headlight to insure the rays of light there-from being projected upon the track in advance of the locomotive to enable the engineer to observe the roadway a safe distance ahead when bearing to the rightor to the left from a direct course.

Having thus described the invention, I claim: t

1. The combination with the :t'rainework of a locomotive engine and the pilot truck, of a headlight pivotally mounted upon the framework, a longitudinal bar pivoted at its ends to the pilot truck and it'ramework, respectively, and having a lateral extensionat the end pivoted to the framework, and a longitudinally movable member extending lengthwiseof the truck and provided at its ends with lateral extensions one of which is pivoted to the lateral extension of the said bar and the other having connection with the headlight to effect a pivotal movement thereof.

i laterally, and a longitudinally movalifle member having end lateral extensions, one of said lateralextensions beingpivoted to the arm of thepost. and the other lateral extension being pivoted to the lateral extensionof the longitudinal bar.

In testimony whereof I aflix my signature.
